TSS incidence unchanged after Rely withdrawal; challenges single-product causation and leaves open multifactorial tampon risks.
Observational (n=197)
p-value: p=>0.2
Active surveillance in Minnesota showed a stable incidence of toxic shock syndrome over 18 months, unaffected by the withdrawal of Rely tampons from the market.
Osterholm et al. (1982) conducted an observational in Toxic shock syndrome (n=197). Rely tampons on the market vs. Rely tampons removed from the market was evaluated on Quarterly distribution of tampon-associated cases (p=>0.2). The number of tampon-associated toxic shock syndrome cases in Minnesota did not significantly differ during the 9 months Rely tampons were on the market (55 cases) versus the 9 months after (59 cases).
